You could just call the HR department of the company you're trying to get hired at, and ask them how detailed they want you to be on your job history. If those temp jobs you so wish to forget didn't contribute to your skills at all, then I'd imagine the company wouldn't have issues if you didn't report them. However, to be on the safe side, call HR. That way, you're covered!
